Results and discussion
- Preliminary study:
- A prelimiminary study showed >50% of mortality at 2000 mg/kg bw, 4 doses has been established to assess LD50 in males: 500, 700, 980 and 1400 mg/kg bw for males and 2 doses in females: 700, 980 mg/kg bw

- Mortality:
- Mortality in males: 0% at 500 mg/kg bw; 0% at 700 mg/kg bw; 60% at 980 mg/kg bw; 60% at 1400 mg/kg bw and 40% at 2000 mg/kg bw
Mortality in females: 20% at 500 mg/kg bw; 20% at 980 mg/kg bw and 100% at 2000 mg/kg bw - Clinical signs:
- The clinical signs observed were a decrease in spontaneous activity for a certain period (from 4 hours to 3 days) relating to the dose administered. Piloerection was recorded after 1 to 4 hours at 700 and 980 mg/kg bw or after 1 to 48 hours at 1400 mg/kg bw.
Dyspnea was noted after one hour in 1 animal at 1400 mg/kg bw.
A reddish vaginal discharge was seen after 24 hours in 2 females at 700 mg/kg bw.
Swelling of the face was observed after 4 and 6 hours in the males at 2000 mg/kg bw.
No clinical sign was observed after 6 hours at 500 mg /kg bw, afer 24 hours in the males at 700 mg/kg bw, after 48 hours in the males at 2000 mg/kg bw, after 72 hours in the surviving females at 700 mg/kg bw and the surviving animals at 980 and 1400 mg/kg bw. - Body weight:
- The body weight gain of the animals was normal between D-1 and D-5 after administration of 500 and 700 mg/kg bw and had decreased slightly after administration of 980, 1400 and 200 mg/kg bw. The body weight gain was normal in all the surviving animales between D-5 and D-15
- Gross pathology:
- The macroscopic examination revealed no abnormalities in the animals found dead during the study or sacrificed at the end of the study
Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- Under test conditions, test item is classified Acute oral tox. cat.4, H302 (CLP regulation)
- Executive summary:
According to a GLP study following TG OECD 401 (1987), 700 > LD50 < 2000 mg/kg bw, a CLP classification Acute oral tox. cat.4, H302 is proposed
